My invention' relates-,to improvements in Atrolley Awheel constructions and is-partieularly eonoerned .irith improved; means for retaining the trolley Wireonthe'ivheel when "the trolley .is A.traversing curve or a .wire

'therefore, :toprevent such-lateral 'disengagement V`-of thewifefwith-theitro'lleyvheel. while, at the same time, -no't-interfering-With the free :rotation of' the v.trolley vvheel and the. tra vel 'A -furthr objexzt' is -to'f pros-'ide 'a construetion'sueh that thfe-trolleywire maybe read-Y i=ly engged with thetrolley-wheel A lfurther .obj'eetto'so arrange the wire 80 retaining means as to permit the wheel to ride over `Ia'iS'Wizteh-*pan and,I at the' s ame time, notte widen the trolley wheel construction in'oiderthat-itmay travel over switch pans of theusual standard construetion.'

lt will he noticed that thestop frames holding;r the stop lags i) a re, at the 'periphery of the trolley lwheel, positioned entirely within thjnvidth of the wheel so that the trolley may he maintained at a width which will traverse readily switch pans o'f'standard size and shape. lt will also he noticed that these arcuate portions 'll of the stop frames l0 are entirely within the periphery of the trolley wheel so that they will not interfere vviththe travel of rolliner of the wheel aloner tllc switrh pans. l `urtlie'rn1ore, it will he notileed that this device may he usediwith trolleys of standard construction bly dsimply rabbeting the groove flanges of t eA 'whee for the reception of the arcuate portions of the stop lugframes. This provides a simple and economical construction and one which maybe employed lwith trolleyso standard construction,

While have herein described a particu- -lar embodiment of the invention, it is to be understood that the same may be alte-red in details and arrangement of parts within the lscope of the appended claims.

What' I claim is: 1. The combination with a trolley harp, of s. trolley Wheel, a pair of stop 'shoulders or lugs carried by said ha located wholly vwithin the periphery of said wheel to prein, of a pair of stopiframe's mounted re- 'p frames having arcuate ortions extending wholly within the gro" e of .the trolley wheel, said arcuateportions having lugs exv tending partially across the upper portion of the periphery of the groove o thetrolley wheel to prevent accidental disengagement of the trolleywheel therewith. l; LA

4. The combination with a trlolley harp, of a trolley wheel, of a pair dit" frames mounted respectively upon the e ds of the spectively on each sideof the fork, said Vtrolley fork, each of saidframes aving an arcuate portion concentric with the axis of the lwheel, the inner faces of the groove of said wheel being rabbeted or inset at opposite sides for the reception of said arcuate portions, each of said 'arcuate portions having a lug adapted to extendpartially across the top of the trolley Wheel groove to pie-l vent accidental disengagement of the trolley wire therewith. I I

5; The combination with a trolley harp of a trolley wheel, of a pair. of frames mounted respectively upon the lendsI pf the trolley fork, each of said fra-mes having an y arcuate portion concentric with the axis of i the wheel, the. inner faces of the groove of said wheel being'rabbeted or inset at opposite sides for the reception of vsaid arcuate portions, each of said arcuate portions having a lug adapted to extend partially across 'the top ofthe trolley wheel groove to prevent accidental disengagement ofthe trolley wire therewith, said arcuate portions of said frames and said lugs being entirely within the periphery of the trolley wheel to v permit free rolling of the perimeter of the trolley wheels over switch pans and the like,

6. The combination with a trolley harp, of a trolley Wheel, of a pair of frames mounted respectively upon the ends of the trolley fork, each of said frames having au arcuate portion concentric with the avis of the wheel, the inner faces of the groove of said wheel being rabbeted or inset at oppox site sides for the reception of said arcuateI ortions, each of said arcuate portions having a lug adapted to extend partially acrossv the topof the trolley wheel groove to-prevent accidental disengagement of the trolley wire therewith, said frames and lugs above the airis of the trolley wheel being entirely Within the width of said wheel to permit the wheel to traverse switch pans of standard construction.

In testimony whereof, I the said JOHN H. Riti-isis, have hereunto set my hand.
